Is homemade vitamin C serum superior?

[Giorgio]

I have read on the derminator 2's creator website that all commercially available serums are inferior and that one should mix vit C serum himself

is it true?

dont make it yourself unless you have PH strips, it will likely be too acidic and irritate your skin
